Btw in regards to the PP8 is it sensitive to cable swaps? Its the one downfall of the E70 I find. Change the cable to 3rd party ones and instantly the E70 sounds different in a bad way.
I had heard that it was and one shouldn't stray from the original cable. I wanted balanced. I got a silver/copper mix which I demoed before buying and it did not change the signature. I'd definitely recommend demo-ing before changing cables but it's possible to find a good match which will not impact the signature.
